New Insights into Wine Color Analysis: A Comparison of Analytical Methods to Sensory Perception for Red and White Varietal Wines
2023 / Journal of Agricultural and Food ChemistryThe Glories method and CIE L*a*b* color space are poorly correlated in the light red high-saturation color area. Non-uniformities in the CIE L*a*b* color space have led to the CIEDE2000 formula, while the Euclidean color distance is still used in wine research. In this study, 112 white and red wines were examined to compare the Glories method, CIE L*a*b, and human ...
